METHODS FOR PREPARING ARTICLES AND ASSOCIATED ARTICLES PREPARED THEREBY

摘要

A method for preparing an article includes applying a first composition on a substrate to form a first layer, and applying a curing condition to a target portion without applying the curing condition to a non-target portion of the first layer to form a first contrast layer. A second composition is then applied on the first contrast layer to form a second layer, and a curing condition is applied to a target portion without applying the curing condition to a non-target portion of the second layer and first contrast layer to form a second contrast layer. A third composition can optionally be applied and cured on the second contrast layer to form a third contrast layer having a cured and uncured portion in the same manner. The uncured portions of these contrast layers are then selectively removed to prepare the article.
